Abstract
This study examined the impact of the transition from Phase 3 to Phase 4 of Japan’s Specific Health Guidance program on same-day health guidance outcomes at Company A. Participants requiring motivational support who completed the program in 2023 or 2024 were included. The completion rate increased from 82.9% in 2023 to 90.0% in 2024. Mean waist circumference changed from +0.37 cm in 2023 to −0.36 cm in 2024. The improved outcomes may be associated with the shortened support period and earlier follow-up intervention introduced in Phase 4. These findings suggest that the revised program contributed to improved participant outcomes.
